Answer:
Following are the response to the given points:
Step-by-step explanation:
For question 5.11:
For point a:
For all the particular circumstances, it was not an appropriate sampling strategy as each normal distribution acquired is at a minimum of 30(5) = 150 or 2.5 hours for a time. Its point is not absolutely fair if it exhibits any spike change for roughly 10 minutes.
For point b:
The problem would be that the process can transition to an in the state in less than half an hour and return to in the state. Thus, each subgroup is a biased selection of the whole element created over the last 
hours. Another sampling approach is a group.
For question 5.12:
This production method creates 500 pieces each day. A sampling section is selected every half an hour, and the average of five dimensions can be seen in a 
line graph when 5 parts were achieved.
This is not an appropriate sampling method if the assigned reason leads to a sluggish, prolonged uplift. The difficulty would be that gradual or longer upward drift in the procedure takes or less half an hour then returns to a controlled state. Suppose that a shift of both the detectable size will last hours . An alternative type of analysis should be a random sample of five consecutive pieces created every hour.
First you put your 2,000 lb. Then you subtract 170lb from it.
2,000 - 170 = 1,830. So you have 1,830 available for freight.
1,830 divided by 69 = 26.5.
Since you can't cut a box in half, and you don't want to overload your lift, your answer is 26 boxes.
So line b is (0,0) and (4, -3/2)
slope = m = y2-y1/ x2-x1
= -3/2 - 0 / (4-0 )= -3/8
now using point slope y-y1=m(x-x1)
m=-3/8 and point is (0,0) to make it easier
y-0 = -3/8 (x-0)
y=-3/8x
so we have the first line done, now another line is parallel to line b which means they have the same slope
line 2 has slope = m = -3/8
and point (0,-7)
using point slope again y-y1=m(x-x1)
y- (-7) = (-3/8) (x-0)
y=(-3/8)x -7
hope that helps and is right
Answer:
x = 5
y = 4
Step-by-step explanation:
multiply the second equation by -1 and add the first equation to eliminate "x"
_____________
Replace "y" in the first equation:
Hope this helps
A line perpendicular to y = (-2/3)x + 5 has a slope of (+3/2).
Use the slope-intercept formula here, and find b:
y = mx + b becomes 1 = (3/2)(8) + b. Multiplying all terms by 2, we get
2 = 24 + 2b. Thus, 2b = -22, b = -11, and the equation of the line is y = (3/2)x - 11.
